TIME-SIGNAL APPARATUS.

Patented July 22, 1913.

Application and mi; 12, 1912. Serial No. 110,902.

Be it known that I, CHARLns SCHAUM- BURG, a citizen of the United States, residing at Olalla, in the county of Kitsap and State of Washington, have invented certain new and useful Improvements in Time- S-ignal Apparatus, of which the following is a s )ccification.

This invention relates to devices actuated by clockwork for giving audible notice of the lapse of predetermined intervals o f time.

The object of the invention is the provision of conveniently adjustable and efficient ap liances of this character which are designed to be utilized for indicating periods of time required in cooking various articles, or to be employed where similar conditions arise.

lhe invention is illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation with the bell and containing case in vertical section, the clockwork therein being shown somewhat diagrammatically. Fig. 2 is a front elevational' View of a portionof the clockwork illustrated in Fig. 1. Fig. 3- is a side elevation of the devices shown in Fig. 1 with the casing and bell in vertical section. Fig. i is a detail sectional view. Fig. 5 isa perspective view of the alarm bell shown detached.

The reference mimeral- 10, designates the front wall, 11 the back wall and 12 the peripheral wall of a casing which is preferably of a cylindrical form and is designed to be secured in an upright position to a suitable support as by screws inserted in apertured lugs 11 provided on the casing. Provided within the casing is a frame comprised of spaced plates 13 and 13 and pillars 14. Supported by said frame is clockwork having a main spring 15 operatively connected to the great wheel 16 which is connected by a train of gearing 17 with an escapement wheel which is associated with an escapement lever 19 and a balance wheel 20. These parts of the clockwork, with the exception of the wheel 16, are constructed and operate in the usual manner, and will require no special description. The wheel 16, however, is characterized by having a portion of its periphery unprovided with teeth. The arbor of the wheel 16 is connected by gears 21 with a hollow post 23 whichis rotatably mounted upon a stud 24 secured to the frame plate 13. The outer end of said post is screw-threaded for engagement with a winding head 25 and intermediate said head and the pinion, the post is formed with a polygonal portion 23 which fits into a hole 26 (Fig. 5) provided in the center of a bell 27. This bell is of a substantially cylindrical form and of a diameter to be inserted within the casing.

28 represents the primary element of a train of wheels which serve upon occasion to rotate an escapement wheel 29 whose teeth engage the pallets 30 of a lever 30 which is provided with a head 30 to serve as a hammer for the bell 27. Upon the outer circumferential surface of the bell is provided a series of graduation marks 31 (Fig. 5) which are successively exposed through a; sigh-t opening 32 (Fig. 1) as the bell is rotated through the medium of the head 25 and the post 23 when the same are employed to wind up the spring.

33 represents a lug secured to or formed on the bell and is arranged to encounter a stop 34 for arresting the rotary movement of the bell and thereby interrupt the operation of the clockwork subsequent to the actuation of the bell ringing hammer 30 To operate the invention the operator turns, in the direction of the arrow A in Fig. 1, the post 23 throu h the'instrumentality of the head 25 to e eot a corresponding rotary movement to the bell and, through the medium of the gearing 21 turns the wheel 16 in the direction indicated by arrows B in Figs. 1 and 2, until one of the numerals 31 on the bell which denotes a selected length of time-for example, twenty minutes-is presented at the sight opening 32 of the casing. By such operation the spring 15 is partially wound up and the gear teeth 16 of the wheel 16 are progressively engaged with teeth of the primary gear 17 of the train of gearing 17 which operatively connects the escapement devices 18 and 19 which regulates the speed of the wheel 16 when the same is subsequently moved in a direction contrary to arrow B when influenced by the spring. The amount of circular movement given to the wheel will regulate the time which it will remain in the mesh with the gear 17 The wheel 16 after being disengaged from the gear 17 is turned by the spring to cause the teeth of the wheel to engage the teeth of gear wheel 28. Whereupon the latter is rotated to effect the driving of the escapement wheel 29 which,

in turn, actuates the hammer 30 to ring the bell and which endures until the lug 83 is brought against stop 34.

From. the foregoing it is seen that spring which actuates the wheel 16 which is alternately engaged with the time regulating devices and the alarm generating devices is successively wound in the successive settings of the register which determines the length of time which will elapse between respective settings of the register and the ringing of the bell.

What I claim is 1'. The-combination of clockwork, an alarm bell, mechanism for ringing said bell, a spring actuated wheel provided with teeth about a portion of its circumference and which are arranged to successively engage the clockwork and the alarm actuating mechanism, and means controlling said wheel whereby the latter is regulated to have the teeth thereof engaged with said clockwork for a predetermined time.

2. In apparatus of the class described, the combination of a rotary bell, a hammer therefor, a wheel in geared connection with said bell, a spring for the wheel, clockwork,

.means for operatively engaging said wheel with the clockwork whereby the latter will be operated through the agency of said spring for a predetermined length of time, and means operative at the termination of such selected time for operatively connecting said wheel with the hammer whereby said spring serves to actuate the hammer.

3. In apparatus of the class described, the combinatlon of clockwork, signal devices, spring actuated means for operating said signal devices, and a wheel provided with gear teeth about a portion of its circumference whereby the aforesaid means may be engaged with the clockwork for a selected time and subsequently engage said signal devices to actuate the same.

4. In apparatus of the class described, the combination of a casing provided with a sight aperture, a bell rotatably mounted within said casing, a register of numerals provided. upon said bell and arranged to progressively pass across the casing aperture in the rotary movements of hell, means to rotate the bell, a wheel rovided with gear teeth about a portion 0 its circumference, a spring for operating said wheel, clockwork adapted to be engaged by the teeth of said wheel when the latter is actuated by the settling movement of said bell rotating means, a hammer for the bell, and means engageable by said wheel for actuating the bell hammer subsequent to the disengagement of said wheel with respect to said clockwork.

5. In apparatus of the class described, the combination of clock-work'including a main spring, a rotary bell, bell-ringing mechanism, and an element arranged to be rotated coincidentally with the bell to wind the clock spring and likewise cause the element to engage the clock-work for a selected time, said element also serving to subsequently effect the operation of the bell ringing mechanism.
